According to a new study, a microscopic freshwater animal known as a “bdelloid rotifer” or “wheel animalcule,” has survived after being frozen for 24,000 years in Siberian permafrost.
“Our report is the hardest proof as of today that multicellular animals could withstand tens of thousands of years in cryptobiosis, the state of almost completely arrested metabolism,” said Stas Malavin, of the Institute of Physicochemical and Biological Problems in Soil Science in Russia, in a Cell Press statement.
